The number of NHS funded sensors that you can receive in every shipment is based on each sensor lasting the full number of days as advertised. We are unable to provide additional sensors. 

We are often contacted to request early delivery of sensors because: 

  • families are travelling  
  • the sensors have all been used, and it is several weeks before the next delivery. 

It is important to report any issues with transmitters or issues with sensors/failed sensors/sensors that have fallen out, so you do not find yourself short of supplies before the next delivery. 

If you have run out of sensors, you will need to go back to finger prick blood glucose testing until your next delivery. It is important to always have a blood glucose meter with the correct, in-date, test strips. If you wish to purchase additional sensors you can do this directly from the company.

Specific information for each company is listed below: 

Dexcom (G6 and G7) 

Early shipment: 

Dexcom will allow you to bring your order forward by 10 days without hospital approval. We will not authorise any shipments to be delivered earlier than this.  

If you are going on holiday, and need earlier supplies, we can ask Dexcom to bring forward your delivery however, your next delivery will remain the same, so it is important to manage your supplies, so you do not run out.  

Reporting failed/faulty sensors: 

This needs to be done via technical support either of two ways: 

  • Complete the online support request at any time – you will need the date that the sensor was inserted, the date it stopped working, the serial number and the transmitter number (if using Dexcom G6).

You can contact DPD or Dexcom to help with this. We will not authorise additional shipments for lost or misplaced orders. Shipping | Dexcom
